Iím looking into buying a 2018 Subaru Forester XT Touring and I see that it features a CVT transmission.I mostly do highway and I always keep my vehicles long term.My question is how long would a CVT transmission last with regular fluid changes at 30K?I would like to keep this Subaru past 150K if possible.Thanks Joe

I think you'll be ok with your CVT maintenance plan.

My understanding is that these things last longer than traditional transmissions.

Just budget for a CVT replacement over the life you intend to get out of it. Then if the CVT lasts take the money and go on a nice vacation somewhere. wink

"We the people" need to set up a "CVT Guide" where lifespans and failures of the different CVT models are logged.

A friend has a 2011 Mitsubishi Outlander (4 cyl.) and at 92,000 we did a pan drop and filter replacement and fluid refresh.

The fluid was the color of dark maple syrup and the filter was completely untouched.
It was stainless steel mesh and perfectly clean. There was no need to change but we did anyway.

Another pal got a Subaru Impreza Sport and we've a date to do the same to his car a few years from now.

I have to admit that I've been way too scared to mess with the CVT in my Subaru, but is a pan drop really possible with these?
My impression was that these are sealed units and the fluid replacement is accomplished by a complicated vacuum out/force in procedure at a specific range of fluid temps. I hesitated about chiming in since I haven't gotten my hands dirty on this part of my car and let a dealer take care of it at 60kmiles, but I have also read a couple of threads on subaruforester.org about doing this job and it didn't sound like a pan drop was an option.
My FXT has a special high torque unit and it even has its own special fluid from Subaru as a result, so trying to make absolutely sure that the dealer used the proper fluid was an extra stressor for me after realizing that another dealer didn't even seem to know that my turbo took 5W30 instead of 0W20. 10kmiles after the 60k service I realized that the wrong air filter had been installed, NA version instead of the part specified for the turbo, so I am really wondering if the CVT got the right stuff...I'm not worried about hydrogen fusing into helium in the CVT as a result, just figure it couldn't be a good thing long term. I'm sure Subaru didn't develop a special fluid for the FXT/WRX CVT just for the heck of it.

Same plan as mine with the wife's Rogue. I've already done the ~30K CVT fluid service (at the dealer) as well as the two differentials (with M1 lube). I plan on keeping it till over 200K if possible (my normal SOP). When I bought the CUV new, I did also purchase a bumper-to-bumper warranty till 10yr/120K miles for $1.3K as some insurance on the powertrain.

I did some research on these as my parents were VERY close to buying a 18 Forester CVT after seeing my 18 Forester 6M. My dad doesn't trust PDU driven AWD systems, but their '13 Escape made it to 80K miles with zero mechanical issues and seemingly would have easily gone another 20K without problems.

It seems the Subaru CVTs (made by Aisin) are extremely reliable. Other than some fluid seepage which Subaru warrantied the entire transmission under 100k miles, they seem to be extremely durable. Also, Subaru is extending the warranty to 100K on most of them.

Personally, I wouldn't have any concerns running a Honda, Subaru, Toyota CVT to 150K miles and would trust it. Nissan CVTs still seem to be problematic. Which is strange, since Nissan and Subaru CVTs are made by JATCO.

The CVT would seem to be less complicated than say a 6 speed automatic.

My 2015 Forester has a 100k mile CVT warranty.

Change the CVT fulid at reasonable intervals.

For what it's worth, our 2014 Forester XT has 75K miles. It is equipped with a CVT.

We occasionally tow a 1K pound empty weight trailer for Home Depot runs. Usually just to purchase drywall, plywood etc. I once towed about 20 boxes to a shipping company that probably totalled to about 1750-2000 lbs. (that includes the weight of trailer) about 60 miles.

One CVT fluid drain and fill at 60K miles. Took about 8 quarts of fluid to get back up to proper level.

Virtus,

PM me if you want to know how I did the fluid drain and fill. It is not complicated at all. The key step is only to have the ability to read the CVT fluid temp. I used the exact procedure as indicated in the Subaru FSM.

These threads pop up often, and usually follow the same pattern. My father has one in his Subaru and we both hate it. What these threads tell me is there is a lot of doubt and uncertainty by many owners about the durability and longevity of these units or these threads wouldn't be popping up as often as they do.

Yeah but when a belt style CVT fails it's usually catastrophic and throws all the metal teeth in the belt all over the place where as with a standard automatic transmission it usually just starts slipping and can be rebuilt.

Seems not. The Subau CVT is made bt Fuji Heavy Industries and is exclusive to Subaru

Fuji Heavy Industries changed their name officially to Subaru earlier this year. So, Subaru makes their own cvt. Subaru is heavily involved with Boeing both on the defense side and on the 777x project.
